Thank you for viewing. RCM Tokina 17mm F3.5 Tokina Lens, single-focus manual lens No electronic contacts I am selling the Pentax lens I have been using to raise funds for a mount change. Please understand that this is for practical use rather than a collection. I used it with K-3III and KP. Optically, there is clouding only in the center. I consulted a repair shop before, and they said it was probably balsam separation. They said it wouldn't affect the image quality much, so it's better to use it as is. I don't think there is any mold, coating peeling, or wiping scratches, but there is dust, dirt, and signs of use on the exterior. If you have any questions, please ask in the comments. Also, this is a used item (treated as junk due to amateur inspection) that will be delivered as is, so please refrain from purchasing if you are sensitive to such things. - Brand: Tokina - Model: 17mm f/3.5 - Lens Type: Single-focus - Mount: K-mount - Accessories: Lens hood, lens cap
